To @Zlio/00771, it 171160,11/ concern:

Be it known that I, J AMEs IRviNG SPENCER, a citizen of the UnitedStates,'residing at Chelsea, in the county of Suffolk and-fState'ofMassachusetts, have tingr/entedii'ain new and useful Improvemen s inFly-Screens; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which forma part of thisspecification.

This invention relates to fly-screens of the sort employing aspring-roller and a sheet or strip of flexible material adapted to bewound automatically thereon; andthe said invention consists in a rollerhaving a rabbet, in combi-A nation with a iiexible eXtensible screenattached to said roller and having re-enforcing bands or folds, andadapted to be wound thereon, and a longitudinally-slotted cylindricalcasing adapted to contain said roller and screen, and having said rollerjournaled in the ends thereof, said casing and its contents be? ingreadily removed from and attached to the wood-work as a single piece.The drawings accompanying this specification represent, in Figure vl, aView of a window and window-frame with my invention applied thereto.Fig. 2 is a horizontal section of the screen and its roller andcontaining-case. Fig. 3 is a view of the roller, showing the groove toreceive the lap of the screen.

In said drawings, A denotes a window-frame,

and B the lower sash of a window.

In carrying out my invention I provide a straight tubular case, D,having a longitudinal slot, E, to permit of the passage of the screen.This case contains a roller, F, journaled longitudinally Within it, andupon the roller the screen is wound by means of a spring suitablyappliedsaid roller being removable withl saidcase. Y

v G represents a screen in the form of a piece of netting of anysuitable material, the inner end of which is secured to the roller F,while its outer end is secured toa strip, H, of wood or other material,containing a ring or catch, I, to engage a stud or fastening secured tothe opposite side of the window-frame. The case D is to be secured in anupright position to one side of the window-frame, as shown, and whenitis desired to screen the lower part of the window the netting G isstretched across .such window and secured to the opposite side of thewindow-frame, as shown in Fig. 1.- 1YVhen released, the netting isautomatically coiled within said case D by the action of the springapplied to the roller. Under ordinary circumstances the netting G, inthe event of a high windblowing into the window, would be swelled outand separated at top and bottom from the window-sash, thereby permittingof entrance of iiies. result, I employ, as one means of effecting thedesired result, a narrow band, J of webbing or other suitable material,whichI dispose at thetop or bottom, or both, of the netting, and so asto somewhat overlap the latter, as shown in the drawings,-the inner endof each band being secured to the roller F, while its outer To avoidthis objectionable end is secured to the. bar H. As the narrow -bothedges of thescreen, thereby providing a fullness of the screen, topermit the latter to be distended bythe wind without separating itsedges from the windowsash. The inner edge of the slot in the case Dserves to maintain the screen in close contact with the window-sash. Itwould be possible to dispense with the case D and put the screen-rollerF directly to the window or door frame; but in this event the rollermust be adapted to approach automatically and recede from such frame asthe screen is wound up or unwound, in order to maintain the screen inclose contact with such frame.

K in the drawings represents a peripheral groove or rabbet in the rollerF, to receivethe increased thickness of the screen at the point wherethe netting and band or the folds of the screen overlap, the object ofthis being to prevent wrinkling or doubling of the screen at this point,which would otherwise ensue as such screen is rolled up.

. Inlieu of placing the case D at one side of the w-indow and adaptingthe screen to be stretched laterally across such window or door,

IOO

the ease may be located horizontally across the top or bottom of suchdoor or Window, and adapted to be raised or lowered with respect to thelatter.

I do not broadly claim ascreen attached to a spring-roller which isjournaled in a removable ease, nor a roller used for sueh purposeshaving arabbet, K, nora slotted removable cylindrical case for such aroller, being aware that these features are not new; but

Vhat I do claim isl The roller F, having rabbet K, in combination with aexible extensible screen attached to said roller7 and havingre-enforcing JAMES IRVING SPEJCER.
